Temptress the French found in New Delhi (7)
I believe the answer is:
delilah
'temptress' is the definition.
(I know that temptress can be written as Delilah)
'the french found in new delhi' is the wordplay.
'the french' becomes 'la' ('the' in French).
'found in' is an insertion indicator.
'new' indicates an anagram.
'delhi' anagrammed gives 'delih'.
'la' inserted inside 'delih' is 'DELILAH'.
(Other definitions for delilah that I've seen before include "She tempted" , "Biblical temptress" , "Samson's destroyer" , "Samsons mistress" , "Woman linked to Samson" .)
